Abstract
Official abstract text for this publication.
In a hybrid vehicle including: an engine having an exhaust system in which a filter that removes particulate matter is provided; a motor configured to generate a driving force for the hybrid vehicle; a power storage device configured to exchange an electric power with the motor; and an electronic control unit configured to control the engine and the motor. When an accumulation amount of the particulate matter of the filter is equal to or more than a predetermined accumulation amount, the electronic control unit is configured to permit fuel cut of the engine when a temperature of the filter is lower than a predetermined temperature, and the electronic control unit is configured to prohibit the fuel cut of the engine when the temperature of the filter is equal to or higher than the predetermined temperature.
First claim
Opening claim text (preview).
What is claimed comprising: 1 . A hybrid vehicle comprising: an engine having an exhaust system in which a filter that removes particulate matter is provided; a motor configured to generate a driving force for the hybrid vehicle; a power storage device configured to exchange an electric power with the motor; and an electronic control unit configured to control the engine and the motor, wherein when an accumulation amount of the particulate matter of the filter is equal to or more than a predetermined accumulation amount, the electronic control unit is configured to permit fuel cut of the engine when a temperature of the filter is lower than a predetermined temperature, and the electronic control unit is configured to prohibit the fuel cut of the engine when the temperature of the filter is equal to or higher than the predetermined temperature. 2 . The hybrid vehicle according to claim 1 , further comprising a generator configured to generate an electric power by using power from the engine and exchange the electric power with the power storage device, wherein, when the accumulation amount of the particulate matter of the filter is equal to or more than the predetermined accumulation amount and the temperature of the filter is equal to or higher than the predetermined temperature, the electronic control unit is configured to cause the engine to be subjected to a load operation or no-load operation when a state of charge of the power storage device is equal to or lower than a predetermined state of charge, and the electric control unit is configured to cause the engine to be subjected to the no-load operation when the state of charge of the power storage device is higher than the predetermined state of charge. 3 . The hybrid vehicle according to claim 1 , wherein the predetermined temperature is set to be lower when the accumulation amount of the particulate matter of the filter is large than when the accumulation amount of the particulate matter of the filter is small. 4 . The hybrid vehicle according to claim 1 , wherein the filter includes a base material which removes the particulate matter and a catalyst which cleans exhaust gas, the catalyst being formed integrally with the base material.
